Unable to work with &Result<T, E>

[rongcuid]

It seems like when I get a &Result<T, E>, miette is unable to handle it at all. IntoDiagnostic requires the error to be Send + Sync + 'static, which is not always possible.

This case occurs when I have a Peekable iterator returning a result type:

let some_iter = (...).peekable();
loop {
    let item: Option<&Result<T, E>> = some_iter.peek(); 
    let inner: &Result<T, E> = item.unwrap();
    let t = inner.into_diagnostic()?; // <-- Error about unable to take *inner because into_diagnostic() takes `self`
    let t = inner.as_ref().into_diagnostic()?; // <- Error about `item` not 'static
    //...
}

It forces me to unwrap because the types just don't check.
